Oklahoma City Thunder forward Serge Ibaka (9) fouls Golden State...

Kevin Durant found Eric Maynor in the corner for an open three-pointer Sunday night, sprinted back to his defensive position, bent over at the waist and couldn't hold back a tiny grin.

With 20 seconds left in the third quarter, Maynor's three-pointer put Durant one assist away from his first career triple-double. By the time he was done for the night, the three-time scoring champion had 25 points, 13 rebounds and 10 assists and finally allowed the smile to broaden.

The Warriors have no doubt improved, but when it comes to playing in Oklahoma City, it's still seemingly bound to end up a laugher.

The Thunder beat the Warriors for the seventh consecutive time at Chesapeake Energy Arena - this time winning 119-109 in front of a sellout crowd of 18,203, which got to watch Durant's all-around dominance despite barely breaking a sweat.

"We played against a very good basketball team that was in the NBA Finals last season, with a couple of very special players and in their building," Warriors head coach Mark Jackson said. "You can't make mistakes. This is a process, and that team went through this same type of experience and learned from it. It's important that we do the same and continue to get better."

The improvements the Warriors (5-5) have made were obvious. They outshot Oklahoma City 52.4 percent-50.6 percent, outscored the Thunder 58-32 in the paint and got more production from their bench (47 points and 13 rebounds to 40 and eight).

The Warriors were beaten on the glass only 40-35 and committed 13 turnovers - only one more than Oklahoma City.

But the Thunder (8-3) have those two special players, Durant and Russell Westbrook, and still have a pretty darn good sixth man in Kevin Martin, whom they acquired in a six-player preseason trade for last season's NBA Sixth Man of the Year, James Harden.

The Warriors did their best to turn Durant and Westbrook into passers, but they consistently found open shooters on the weak side, which helped the Thunder knock down 13 of 20 three-point attempts.

Westbrook scored a game-high 30 points and added seven assists and five steals. Martin came off the bench for 23 points, including five three-pointers and five assists.

"Obviously, you try to find bright spots in a game like this," said Warriors point guard Stephen Curry, who scored a team-high 22 points to go along with six assists. "They're the reigning Western Conference champs, and they're playing well at home. We wanted to compete and find a way to be in it at the end, but if they shoot the ball like that from the three-point line and we give up 119 points, that's not going to cut it."

Warriors power forward David Lee had 19 points and 10 rebounds for his fifth double-double in the past six games. He also dished out five assists, including finding Curry for a three-pointer that trimmed a 22-point deficit to 105-98 with 5:59 remaining in the fourth quarter.

Serge Ibaka, who had 16 points and eight rebounds, responded with a jumper, Curry missed an open three-point try, and Martin did not. Just like that, Oklahoma City pushed its lead back to 110-98 and led by double digits the rest of the way.

"That was kind of the theme of the night," Lee said.

Especially because Durant was the one who passed the ball to Martin.

Briefly:Richard Jefferson didn't return after going down with a strained right calf and is listed as questionable for Monday's game at Dallas. Having already lost Brandon Rush for the season with a torn anterior cruciate ligament, the shooting guard/small forward spot is one of the Warriors' thinnest, but rookie Draymond Green had his best game with nine points and five rebounds.
